Sometimes when i even stop at a red light the temp starts going up. When i start moving the temp goes down. what could be the problem?

Radiator cooling fan(s).
I already had it replaced! What else could it be?
Ok but is it working like it should? That is the only thing to cool the engine when stopped. Ram air at road speed does the cooling. Only other possible cause is the water pump but not likely.

Check fan clutch c/o and that should help with your problem.

Probably condenser fan, if not have your radiator checked....water pump would be last resort...doesn't sound like a thermostat.
